IMPROVEMENT IN SEEDING-MACHINES.

Specification forming part of Letters Patent No. 23,183, dated March 8,18.79.

w To all 'whom it may concern:

' being had to the annexed drawings, makinga part of this specication,in which- Figure l is a side sectional view of our invention, taken inthe linear rv, Fig. 2. Fig. 2 is an inverted plan ot' the same.

SimilarI letters of reference indicate corresponding parts in the twogures.

This invention relates to an improved means for forming thefurrowswhichreceive the seed, as hereinafter fully shown` and described, whereby allrubbishsuch as roots, weeds, and the remains of previous crops-isprevented from interfering with the proper forming of the furrows, andthe ground, when planted, left in proper state for the early use ot' thecultivator or other implement used in subsequent cultivation.

To enable those skilled in the art to fully understand and construct ourinvention, We will proceed to describe it.

A represents a rectangular frame, the back part of which is supported bywheels B B and the i'ront part supported by a pair of wheels, G C, onthe axle c ot' which a bar, b, of the trame A rests. To the axle a otthe wheels U U the draft-pole D is attached. To the axle a., at itscenter, a vertical rod, c, is attached, said rod passing loosely throughthe bar b.

On the frame A seed-boxes E E are placed.

These seed boxes may be provided with anyV suitable seed-distributingdevice, and to each seed-box a seed-spout, F, is attached. On the frameA the drivers seat G is placed, and a rope or chain, H, is attached tothe front end ot' the bar b and passes through the upper end of the rodc and is secured to the seat G.

In the front part of the frame A there are attached two standards, H H.These standards are secured in the frame by screws d, which may passthrough either of a series of holes, e, made in the standards. By thismeans the standards H' H may be. adjusted higher or lower in the frameA. a

To each standard H' a supplemental seedtube, I, is attached, and thesetubes I fit over the lower ends ot' the spouts F, and to each standard Htwo wings or mold-boards, JJ, are attached in oblique positions, onebeing at each side of the tubes I, as shown clearlyin Fig. 2. The wingsor mold-boards J J are connected at their front ends, and they areattached to the standards H by bolts f, which pass horizontally throughthe frontendsof the mold-boards and through slots g in the standards H".This mode of connecting the wings or mold-boards to the standards admitsot' a vertical adjustment of the former, as will be clearly understoodby referring to Fig. I.

'Io the lower end of each standard H H a V-shaped share or cutter, K, isattached by a pivot, li. To the front end of each share or cutter K aknife, L, is attached by a pivot, t, and to the outer end of each knifea standard, M,is permanentlysecured,`said standard passin g up throughguides j attached to the frame A.

The operationis as follows: As the machine is drawn along the seedpasses down the spouts F into the tubes I and dropsinto furrows made bythe shares or cutters K, and the knives L penetrate the ground and cutall roots, Weeds, sticks, and the remains of previous crops that may beon or in the soil and in the paths of the sharesK. The knives Ltherefore facilitate the work of the shares and insure their perfectoperation. The wings or mold-boards J J grade the surface of the groundat the edges of the furrows, so that the top and bottom of the i'urrowswill be parallel and the seed covered at a uniform depth.

It will be seen that the depth of the furrows may be regulated, asdesired, by adjusting the standards H higher or lower, and that theknives L may also be adjusted higher or lower to correspond with theposition ot' the shares or cutters K, the standards M being secured atany point by adjusting the guides j. Ihe seed, it will be understood,falls from the tubes I directly behind the shares K.

When the machine is to be turned at the ends ot rows the driver on theseat G, by throw face of the ground.

share K, wings or mold-boards J J, with or without the tube I, arrangedfor joint operation,

ing` himself slightly back and drawing on the rope or chain H, willraise the frontof the frame A, and thereby elevate the shares K, wingsor mold-boards J J, and knives L above the sur- DANIEL MARKHAM.
